1 Claim.

This invention relates to air humidifying devices and more particularlyit pertains to that type of device which is suspended from heating unitssuch as radiators and filled with water to supply moisture to the air ina compartment being heated.

All such devices, with which I am familiar,-

have many disadvantages among the most pertinent of which is theirtendency'to'spring a 1n leak. This tendency results from the manner inwhich such devices are constructed.

All such devices as heretofore constructed, with which I am familiar,are formed by placing two sections together with a flange of oneoverlapping the other and a soldering of the overlapping flanges. Asgenerally constructed these devices have square corners and aretherefore more easily subjected to rupture from the impact or-blowsreceived upon the corners and upon their sides particularly in'thelocation of the soldered joint or seam.

It is an'object of the present invention so to construct a device of theafore-mentioned char acter that it will be sturdy and will withstandimpacts resulting from use, without rupture of the joints.

It is a further object of the invention so to construct the device thatit will not only be liquid-tight when first manufactured, but will llmaintain said liquid-tight condition throughout use.

It is still a further object of the invention,

7 so to construct the device that it will present an attractiveappearance. 1

.3 With the above and other objects in View, reference will be had tothe accompanying drawing and the following specification and claim.

In the drawing:

Figure 1 is a fragmentary. diagrammatic view of a radiator illustratinga humidifier constructed in accordance with the present invention, inposition thereon, I

Figure 2 is airagmentary plan View on an enlarged scale illustrating oneof the corners 3 of the humidifier,

Figure 3 is a distended perspective view illustratingthe two parts orelements from which The section It! is formed from sheet metal and isshaped, preferably by die stamping, to provide a flat wall portion l2defined on three sides by flanges which are designated I3, I4 and IS inthe drawing-and which extend in planes at 5 right angles, orsubstantially so, with respect to the wall I2. In the stamping of thesection II), the corners are rounded as designated by the referencenumeral I6 and the free edge of each of the flanges l3, I4 and I 5 andthe rounded corners-l5 are bent backwardly upon their respective flangesto form a locking flange H.

The member H is shaped to provide a wall 20 which is corrugated asillustrated. Defining three sides of this corrugated member ll, there 10are flanges ii, 22 and 23. This member II is likewise formed withrounded corners 24 and each corrugation ends adjacent the flange 22 inan angular end wall 25. Each of the flanges 2|, 22 and 23, as well asthe curved corners 24, is formed with locking flanges ZG-Which flanges26 are bent backwardly upon their respective panels as illustrated.

In assembling the parts, the two elements l0 and I l are placedtogether'with the locking flanges 26 of the member l l interlockedbehind the looking flanges ll of the member l8. With the parts in thisposition, they are subjected to'a suitable operation, preferably bydies, to crimp the interlocked flanges 26 of the member' H with theirrespective locking flanges ll of the member [0.

This method of procedure provides a relatively tight joint. between themembers ill and H and after it has been thus far completed, the entirearticle is dipped in a hot galvanizing bath to deposit thereon agalvanized coating such as 30 in the drawing.

As designated by the reference character! the galvanizing bath, when itis deposited upon the article, completely encloses the interlocked jointbetween the elements I0 and H thus rendering the device water-tight inevery respect.

I The device in its finished state presents rounded corners and is thusable to withstand shocks and abuse without rupture, to a far greaterextent than is possible in these devices as ordinarily constructed. y

In use, the device is suspended from a radiator with the corrugated wallof the element ll fitting between the coils of the radiator. Thesuspending means consists of two hooked members ll] which are removablyassociated with the device by engagement of hooked ends, not shown, withstruck out ears 4| in the conventional manner.

In its completed state the device is in the form of a receptacle forwaterQand in its operative position is maintained filled with water tosupply moisture.

Having thus described the invention what is claimed as new is:

A metallic receptacle of the character described comprising two membersone of which is smaller than the other thereby to permit one member totelescope within the other, and said members adapted to be securedtogether to form the receptacle, each of which members has a single sidewall, two end walls and a bottom wall, the bottom wall of each memberbeing connected to its respective end walls through the medium ofrounded corners, an inwardly projecting flange extending from the freeedge of each of the side walls and the bottom wall of the larger member,and an outwardly extending flange extending from the free edge of eachof the side walls and the bottom wall of the smaller member, saidinwardly and outwardly projecting flanges being adapted for interlockingengagement when the smaller member is telescoped within the largermember to secure the members together in receptacle forming relation.
